Python具体实现自动测试
安装selenium模块
pip install selenium
代码
# -*- coding: utf-8 -*-from selenium import webdriverfrom selenium.webdriver.remote.remote_connection import RemoteConnection# 创建远程连接selenium gridremoteconnection = RemoteConnection('http://zalenium-zalenium.demo.example.com/wd/hub', keep_alive=False,
resolve_ip=False)
driver = webdriver.Remote(command_executor=remoteconnection,
desired_capabilities={ 'browserName': "chrome", 'video': 'True', 'platform': 'LINUX', 'platformName': 'LINUX'
})try:
driver.implicitly_wait(30)
driver.maximize_window()
driver.get("http://www.baidu.com") assert u'百度一下，你就知道' in driver.title
kw_input = driver.find_element_by_id('kw')
su_button = driver.find_element_by_id('su')
kw_input.clear() # 输入关键字Openshift
kw_input.send_keys('Openshift')
su_button.click()finally:
driver.quit()说明：
创建RemoteConnection时需要设置keep_alive=False及设置resolve_ip=False。
resolve_ip默认为True，它会解析senelium grip服务器的ip,便通过Ip去访问。我们知道Openshift的应用是无法使用ip来访问的，必须使用域名。所以需要将resolve_ip设置为False。当然，如果我们部署zalenium中的service使用nodeport将4444端口暴露出去的resolve_ip可以使用默认值。
